Superconducting materials will expel an induced magnetic field as it creates internal fields that exactly cancel out the induced one. You’d still need some sort of “rails” to created the induced field and to move it to generate forward motion.
That is for the Meissner effect I think. I guess what I was thinking is to use the SC to create an incrediblely strong electromagnet to repel the Earth’s magnetic field. But it looks like we are orders of magnitude away from that

The earth’s magnetic field is so weak that you’d be repelling something the mass of a compass needle.
